Plants with male and bisexual flowers on the same plant are better mothers
What would be the opening chapter of the Kamasutra of plant sex? A good pick would be a description of the numerous ways in which plants arrange their sexual organs: from both sexes in the same flower to sexes separated in different flowers or individuals.   view more (2007-05-01)

Flowers shape themselves to guide their pollinators to the pollen
Why do flowers specialize on different pollinators? For example, both bats and hummingbirds pollinate plants in tropical forests; why adapt to just one instead of using both? Biologists often assume that tradeoffs contribute to such specialization (the jack of all pollinators is master of none),... view more (2007-04-04)

The cost of long tongues
Orchid bees use their extraordinarily long tongues to drink nectar from the deep, tropical flowers only they can access.   view more (2007-04-17)

How did bilaterally symmetric flowers evolve from radially symmetric ones?
The researchers found that plants bearing bilaterally symmetrical flowers were more visited by pollinators and had higher fitness, measured by both the number of seeds produced per plant and the number of seeds surviving to the juvenile stage, than plants with radially symmetric flowers.   view more (2006-10-03)

John Innes Scientists Scoop Gold Medal at Chelsea Flower Show
The exhibit is a "fashion show" which explains how jumping genes, virus disease infection and bizarre chimeras cause the beautiful foliage and flowers we admire in plants. The display features a collection of beautiful common and unusual plants as "models" on the fashion catwalk.   view more (1999-05-25)

Predators: an overlooked player in plant-pollinator relationships
Biologists have long recognized that predators can help to shape ecological communities -- wolves promote the growth of young trees through predation on moose, otters keep kelp forests thriving by preying on sea urchins, etc. Yet we have seldom considered the consequences of predation on animals... view more (2003-08-13)

Flowers' fragrance diminished by air pollution, University of Virginia study indicates
Air pollution from power plants and automobiles is destroying the fragrance of flowers and thereby inhibiting the ability of pollinating insects to follow scent trails to their source, a new University of Virginia study indicates.   view more (2008-04-11)

Columbine flowers develop long nectar spurs in response to pollinators
In flowers called columbines, evolution of the length of nectar spurs--the long tubes leading to plants' nectar--happens in a way that allows flowers to match the tongue lengths of the pollinators that drink their nectar, biologists have found.   view more (2007-06-08)

Detecting poisons in nectar is an odour-ous task for honeybees
Though many spring flowers have bright advertisements offering sweet rewards to honeybees, some common flowers have not-so-sweet or even toxic nectars.   view more (2007-04-02)

Study explores plant phenotypic plasticity belowground
When we think of organisms actively searching for resources (foraging) we generally think of things like wolves stalking elk or butterflies finding flowers. Why don't we also think about plants growing roots through the soil?   view more (2005-07-27)

Cranfield University is blooming marvellous
Thanks to researchers at Cranfield University, your next bouquet of flowers should stay fresher for longer. The Geraldton waxflower - a popular filler in floral bouquets in the UK - is prone to infection and disease which causes the flowers to fall, leading to disappointed customers. Researchers at... view more (2003-10-03)

Wild Bees Make Honeybees Better Pollinators
Up to a third of our food supply depends on pollination by domesticated honeybees, but the insects are up to five times more efficient when wild bees buzz the same fields.   view more (2006-09-22)

Bees go 'off-color' when they are sickly
Bumble-bees go 'off colour' and can't remember which flowers have the most nectar when they are feeling under the weather, a new study from the University of Leicester reveals.   view more (2008-07-16)

Warmer springs mean less snow, fewer flowers in the Rockies
Spring in the Rockies begins when the snowpack melts. But with the advent of global climate change, the snow is gone sooner. Research conducted on the region's wildflowers shows some plants are blooming less because of it.   view more (2008-03-06)

How size matters
The beauty of nature is partly due to the uniformity of leaf and flower size in individual plants, and scientists have discovered how plants arrive at these aesthetic proportions.   view more (2007-12-13)

Nature surrenders flowery secrets to international team
The poet Dylan Thomas wrote, "The force that drives the green fuse drives the flower." Now, a team of international scientists has unlocked some of the secrets of that force: it has described the rules that govern how plants arrange flowers into branching structures, known in technical... view more (2007-05-25)

Grand Canyon may be as old as dinosaurs, says new study
New geological evidence indicates the Grand Canyon may be so old that dinosaurs once lumbered along its rim, according to a study by researchers from the University of Colorado at Boulder and the California Institute of Technology.   view more (2008-04-11)

Why do insects like to eat some plants more than others?
In a study appearing in the forthcoming issue of The American Naturalist, Tom E. X. Miller, Andrew J. Tyre, and Svata M. Louda (all of the University of Nebraska, Lincoln) examined herbivore dynamics, specifically why plants aren't all eaten at the same rate.   view more (2006-11-14)

Patriotic new lilacs introduced
Lilacs. The word evokes memories of promising spring days and visions of colorful, perfumed blooms. Lilacs have long been well-loved staples in America's yards and gardens, and have played a storied role in U.S. history.   view more (2008-07-02)

A new idea for how anti-aging products delay ripening of fruit and wilting of flowers
When plants encounter ethylene, a gas they also produce naturally as a hormone, the result is softening and ripening in the case of fruit, and wilting and fading in the case of flowers - all of which ethylene promotes.   view more (2008-05-05)

Spread of plant diseases by insects can be described by equations that model interplanetary gravity
Researchers from Penn State University and the University of Virginia show that the spread of diseases by insects can be described by equations similar to those that describe the force of gravity between planetary objects.   view more (2006-09-05)

Which came first, the moth or the cactus?
It's not a good idea to put all your eggs in one basket- unless you're a senita moth.   view more (2007-08-15)

Love calls from the bottom
Some men send flowers, others send chocolates. But one species of fish has a rather unusual method of seducing the opposite sex. Researchers at the Centre of Marine Science, University of Algarve, Portugal, have been studying how the peacock blenny fish secretes pheromones – chemical... view more (2002-04-04)

Simulating kernel production influences maize model accuracy
Recently, researchers at Iowa State University discovered a way to increase the accuracy of a popular crop model. By zeroing in on early stages leading up to kernel formation, scientists believe they can help improve yield predictions across a variety of environmental conditions.   view more (2007-09-24)

Natural pesticide impairs bumble bee foraging ability
Pesticide levels previously thought to be safe for pollinators may prove harmful to wild bee health, according to research published in Pest Management Science this month.   view more (2005-05-06)
